Definitions

• the present invention relates to a method for preventing piglets from suffocating under the dam in a brooding pen provided with a particular bay or equivalent space reserved for the dam, the said method comprising a suitable sensor, for example a photocell, for detecting when the dam stands up and lies down.
• a suitable sensor for example a photocell
• the purpose of the present invention is, among other things, to avoid the above drawbacks.
• the invention is based on the idea that in the brooding pen is arranged a situation with strongly opposed conditions with respect to the piglets. It is generally known that piglets do not like draft nor cold, whereas they are drawn to warm, light and draftless places. Accordingly, the invention is characterized by the novel features presented mainly in the Patent Claim 1. The characteristic features of the apparatus according to the invention are enlisted in the Patent Claim 3.
• Figure 1 is an illustration of one preferred embodiment of the invention in perspective view.
• Figure 2 is an illustration of the apparatus of Figure
• the arrangement according to the invention comprises a narrow bay 1 or similar space reserved for the dam, which space forms part of the brooding pen.
• the bay is a narrow bay 1 or similar space reserved for the dam, which space forms part of the brooding pen.
• a photocell which consists of a suitable receiver
• the horizontal pipe 4 At the other end of the bay 1, comparatively near to the ground, is placed the horizontal pipe 4.
• the pipe 4 is provided with several small perforations 8 , through which air can be blown evenly in narrow jets to the space under the dam when it is standing up.
• the air is blowed with the blower 5 or with a similar device through the vertical pipe 6 further to the horizontal pipe 4.
• the apparatus functions in the following manner. While the dam is lying down in the bay 1, the piglets can suck it in a natural way. When the dam stands up for example to drink or eat, its back obstructs the ray of light coming from the photocell 2, 3. As a consequence the blower 5 is switched on and starts blowing air under the cam through the perforations 8 of the horizontal pipe 4, in this case only from one direction A. Thus under the dam is formed a condition which is unpleasant for the piglets, and they turn to the direction of the air flow. On the opposite side of the brooding pen, outside the bay 1, in the direction of the air flow, is located a heat lamp 7, which further emphasizes the contradictory circumstances. When the dam lies down again, the receiver 2 of the photocell detects the ray. of light coming from the transmitter 3, the blower 5 stops operation and the piglets return to suck the dugs of the dam.
• the apparatus 4, 5, 6 of the invention and the detector 2, 3 attached to it can form a stationary part of the bay 1.
• the horizontal pipe 4 can be replaced by the pipe 4' belonging to the structure of the bay 1, which pipe 4' can be perforated like the horizontal pipe 4.
• the apparatus with the detector can form a separate device to be attached to the bay, as presented in Figures 1 and 2.
• blower 5 is arranged in connection to each apparatus. It is also possible that several separate apparatuses have the same blower in common. In these cases, a compressor or other generally known device which produces pressure air, can also be used instead of the blower.
• the blowing of the air under the standing dam can be carried out, except from blowing it through the horizontal pipe 4, 4' provided with perforations 8, also through one or several suitable nozzles which efficiently spread the air flow in a fanlike fashion.
• blowing of the air in the brooding pen can, if desired, also be arranged to take place from a direction other than that of the above embodiment, or from several directions.
• the essential feature of the invention is that the air flows away from under the dam standing in the bay or equivalent space.
